To all whom it may concern Be it known that I, PAUL J. SIMMIEN, a citizen of the United States, residing at Indiana olis, in the county of Marion and- State Indiana, have invented certain new and useful Improvements in Devices for- Perforating Paper, of which the following is a specification.

- This invention relates to record making mechanisms for train despatching and signal systems and particularly to the means employed to perforate a continuously mov- "-"the perforatingneedle of the recording ing record sheet at a train despatchers office to indicate the time at which a particular vehicle was at a particular place and.

thereby set into operation electrical means for energizinga solenoid coil.

The details of the despatching system are not material to the present invention which relates merely to the manner of operating mechanism, and its novelty resides in the construction and adaptation of the parts as will be more fully hereinafter'pointed out. I.

. In general, the perforating needles are arranged 'in series in front of. a moving sheet of paper. actuated by suitable clockwork.

. Each needl'eis secured to, or made integral with, an armature arranged inside of an electric coil, which .is magnetized in' the usual way current. is on. c

The object of the construction is to cause the needle to moveforward to perforate the record sheet and thenwhile the current is still on to have the needle withdrawn from the paper. Such withdrawal is effected either by the tension of a spring acting against or'with the magnetism ofthe coil.

,When a solenoid of the-kind described is energizedand become's'a magnet the armature inside is sucked to a neutral position.

Any movement-of the armature-must there-'- after' be against the magnetic force tending.

to keep itin Such position. Advantage is taken'of thisto produce the result .that the v moment, the .current is turned'on the needle is hurled forward against the paper and perforates it, bein carried by its momentum rentis'still on the needle is withdrawn and beyond-the neutra point, and while the curwill not remain sticking in thepaper.

when the circuit is closed and the in the act of: perforating the paper, and

Ifig. 3 is a similar view showing the p'osit1on to which the needle is withdrawn, with the current still on.

The views are all diagrammatic in charac-' ter and constructional details are omitted'in orderto clari the description.

In the drawings, represents a needle of which 11 is thepoint, 12 is an armature to which the needle issecured or with which it is made integral. 1 13 is a shank terminating in a cross a 14' constituting a stop. The armature is adapted to be reciprocated between two bearings 15 and 16, which serve as guides to directi the course of the needle: A spring 17 isc'oiled around the shank, 13, and impin'ges against the bearingllfi'and arm 14. Surrounding the 'armature,12is an electric coil 18 having terminals 19 and '20 and with a switch 21 in circuit therewith. 22. represents a recordv sheet which is adapted to be moved by clockwork or other suitablev mechanism a proper distance in front of the needle.

When the current isiofi and the switch 21 I is open the armature and needle arein the 7 positions shown in Fig. 1. -.When the cur-' rent is turned on, the tendency of the magnetic force in the coil is to move the arma- V ture to a neutral position (as shown in Fig.

3) ,but after the armature moves it acquires a momentum and moves beyond this neutral position and carriesthe needle to a point where itwill perforate the paper, but as the current continues the armature is sucked iniso doin' b the s ring,17.

.amarking implement, and means actuated by the energization of the coil to cause the marking implement to operate on a record sheet and bewithdrawn therefrom while the coil is still energized. v

2. In apparatus of the character set forth, the combination with a solenoid coil, of means for supplying current to the coil con tinuously for a material period of time, a marking implement, and an armature car-- rymg the marking implement and actuated by the energization of the coil to cause the marking implement to operate on a record supplying means being independent of the armature.

3. In apparatus of the character set forth the" combination with a solenoi coil, 0 means for supplying current to the coil continuously for a material period of time, a marking implement, and an armature carrya ing the marking implement and actuated by means for supplying current to the coil con- 1 the energization of the coil to cause the marking implement to operate on the record sheet, said armature and implement being suificiently heavy to cause the armature to be carried past the neutral position and the implement to operate on a record sheet and then be withdrawn'therefrom while the coil is still energized.

4:- In apparatus of thecharacter set forth the combination with a, solenoid coil, 0

tinuously for a material period of time, a

marking implement, an armature carrying the marking implement and actuated by the energization of the coil, and means for holding the armature at one side of the neutral position of the same when the coil is deenergi'zed, said armature when actuated. by the energization of the coil being sufiiciently heavy to cause it to be carried by its momentum past the neutral position, to thereby cause the marking implement to operate on a record sheet, the armature then returning to the neutral position and withdrawing the implement from the record sheet while the coil is still energized, said current supplying means being independent of the armature.

In apparatus of the character set forth, the combination with a solenoid coil, of means for supplying current to the coil continuously 'fora material period oftime, a marking implement, an armature carrying the marking implement and actuated by the ergization' of the coil, and a spring ,for holding the'armature at one side of the neutral position of the same when the coil is deenerglzed, said armature when actuated by the energization of the coil being sufiiciently heavy to cause it to be carried by its mo mentum past the neutral position, to thereby cause a record sheet, the armature then returning to the neutral position and withdrawing the the marking implement to operateon' implement from the record sheet while the coil is still energized.

6. In apparatus of the character set forth, a solenoid coil adapted to be located adjacent to a record sheet, means for'energizing the coil for a material period of time, an armature operating in .the coil, a marking implement carried by the armature and movable therewith into and out of contact with such record sheet, means for normally holding the armature 'at one side of its neutral position in the coil with the marking implement out of contact with'the record sheet, said means permitting the movement of the armature by the coil, and said armature being of sufiicient weight to cause it when so actuated to pass the neutral position and carry the marking implement into contact with the record sheet and then return to withdraw the marking implement from the record sheet while the solenoid coil is still energized. 1
